"Default" removes all device tabs and deletes all stored configuration data, including all user presets,
from the Windows Registry.
TIP: CW KEYER can be reset to the factory configuration by selecting Default Router Settings
followed by Device | Store as Power-up Settings to save the defaults to the keyer's memory.

A urs file can be used only with the device for which it was generated (the file contains the unit serial
number) on a computer with same port assignments.
